Synthetic Applications of Intramolecular Insertion in Arylcarbenes. VI. Ylid Rearrangements in Pyrolysis of o-Alkylthiophenylcarbenes

Crow, Wilfrid D.,Pang, Y. T.

, p. 1903 - 1914 (2007/10/02)

Low-pressure thermal generation of a range of o-alkylthiophenylcarbenes produces, in addition to the normal insertion products, styrenes and 1,3-dihydrobenzothiophenes-clearly arising from rearrangement.The main features of their mechanism of formation are established by deuterium-labelling studies: in both cases participation by S-ylids implicated.
